Struct for holding guid references
struct FFastArraySerializerGuidReferences
TArray< uint8 >
Buffer
Buffer of data to re-serialize when the guids are mapped
TSet<FNetworkG...
MappedDynamicGUIDs
List of guids that were mapped so we can move them to unmapped when necessary (i.e. actor channel closes)
int32
NumBufferBits
Number of bits in the buffer
TSet<FNetworkG...
UnmappedGUIDs
List of guids that were unmapped so we can quickly check
